Abstract

PURPOSE:To obtain high display grade with the orientation films of high heat resistance and stability and long life by using the crosslinked matter of the ladder type organo silicone polymer having phenyl groups for the orientation control film. CONSTITUTION:The polyphenylsilsesquioxane of the formula [R is groups of high heat resistance, mainly phenyl groups, etc. and the groups crosslinkable to ladder type through post treatment such as heating, etc.] whose contents of crosslinkable groups such as aminophenyl groups, vinyl groups, etc. of -(CH2)n-OH, 0(CH2)n NH2 in R and 1-5 in n and which has the heat resistance of the extent that crosslinking reaction occurs at 200-400 deg.C and polymer does not decompose at 450- 500 deg.C is used for the orientation control films 4 of the liquid crystal display device constituted by glass substrates 1, Na<+> ion barrier layers 2(this may not be used), transparent conductive films 3, polarizing plates 6, sealing materials 7 and liquid crystal 5. These orientation control films do not cause degradation in orientation characteristic through heating, etc. because their heat resistance is high.
